ROOFING-BRACKET.

Specification of Letters Patent.

Application filed May 18, 1914. Serial No. 839,420.

To all whom it may concern Be it known that 1, WILLIAM H. BOYD, a citizen of the United States, residing 'at Mount Victory, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Roofing-Brackets; and I do declare the following to be a full, clear, invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

This invention relates to adjustable brackets designed for use in shingling or slating roofs or in performing any repairs that may be necessary on the roof of a building in the course of construction or already completed, for the purpose of supporting a scaffold and is adjustable for use with equal effect upon a roof of any inclination.

The object of this invention is to provide an inexpensive, strong, light and portable bracket of few parts that may be quickly adjusted in place and the support locked automatically to render it safe to prevent all danger of its becoming accidentally released.

Another object of the invention is to provide an adjustable nail strip to adapt the bracket to be used in connection with different lengths of shingles and different kinds of roofing.

With these and other objects in view the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described and claimed.

In the accompanying drawings: Figure 1 represents a top plan of a pair of these improved brackets in position on a roof; Fig. 2 is a longitudinal section taken on line 2-2 of Fig. 1. Fig. 3 is a longitudinal section of the bracket in its operative position taken on line 3-3 of Fig. 1. Fig. 4 is a horizontal section of the bracket taken on line 4l4 of Fig. 2. Fig. 5 is a top plan view of the device in folded position: Fig. 6 is a longitudinal section on line 6-6 of Fig. 5: Fig. 7 is a transverse section taken on line 77 of Fig. 6: Fig. 8 is a transverse section of the platform taken on line 8-8 of Fig. 2: Fig. 9 is a transverse section taken on line 9-9 of Fig.2. Fig. 10 is a detail perspective view of the gravity pawl. Fig. 11 is a transverse section taken on line 4-4 of Fig. 3.

In the embodiment illustrated a base plate 1 is shown preferably constructed of galand exact description of the to form guides for to be described.

wardly to offset it from the plate 1 to form guides for slidably to be described.

Two rack bars 6 are arranged in parallel relation on the inner face of the plate 1 adjacent the side flanges thereof and are here shown in the form of angle irons, one flange of which is bolted to the base plate and the other extends outwardly and is provided with a plurality of inclined notches or recesses 7 for adjustably supporting one end of the brace bar or plate hereinafter described.

The nail strap 8 is herein shown in the form of a Tshaped strip the head 9 of which is folded to form a reinforcing head 10 here shown substantially triangular in cross section and which is designed to engage one edge of one of the straps 4 to limit the outward movement of the strap 8 which mounted under the straps 4 be tween their lower faces and the inner or upper face of the base plate. Three of the straps 4 are here shown but it is obvious that any desired number may be employed and that the strap 8 may be engaged with two or more as desired according to the distance which it is desired to connect the bracket from its point of support. The free end of the shank of the strap 8 is provided in one edge with a plurality of inclined recesses or notches 11 which are preferably larger at their inner ends to form recesses for engaging nails driven into the roof on which the bracket is to be supported and which holds said strap reliably in engage ment with said nails. The openings from these enlarged portions of the recesses are inclined toward the head of the strap and thereby prevent all danger of said recesses becoming accidentally disengaged from the supporting nails.

Pivotally mounted at one end of the base plate 1 between the flanges 2 thereof is a supporting platform 12 here shown in the receiving a nail strap 8 Pa nte F 2, 1 1.

yeo

form of a rectangular plate having side flanges 13 the edges of which are folded inwardly against the inner faces of said flanges to reinforce them and provide sufficient strength to the platform for supporting the weight of the scaffold. The inturned portion of these flanges is cut away at one end and the ends of the flanges recessed to receive a pintle 14 which pivotally connects the platform with the base plate and on which between the flanges of said platform is loosely mounted a combined spacing sleeve and hinge member 15 which is formed by rolling the end of the platform plate 12 inwardly between its flanges. The other end of said plate is similarly rolled to form a bearing 16 for receiving a pintle 17 which pivotally connects said platform plate with the supporting brace 19 to be described. Fixed to the inner face of the platform plate is a laterally extending member 18 substantially V-shaped in cross section with flanges at its opposite edges which serves to attach said plate by riveting or otherwise. A brace 19 is here shown in the form of a rectangular plate having side flanges 20 provided near one end thereof with registering apertures 21 through which the pintle 17 is adapted to extend for pivotally connecting said brace with said supporting platform. The free end of this brace is rolled outwardly to form a reinforcing bead or rib 22 which is adapted to be engaged with one of the pairs of registering notches in the rack bars 6, it being obvious that this bead may be enaged with any pair of the registering notches formed in the rack bars 6, whereby the platform may be adjusted at any desired or suitable inclination. Loosely slidable on the inner face of this base plate 19 is a locking element 23 here shown in the form of an L-shaped plate the long arm of which is slotted longitudinally as shown at 24, the short arm extending outwardly to form an operating finger or handle 25. This plate is slidably mounted on a headed stud 26 arranged near the free end of the brace at one side thereof in position to permit the free end of the long arm of said plate to automatically drop down into one of the notches in which the bead 22 of the brace is seated, passing between the upper wall of said notch and the adjacent face of the brace plate and thereby securely locking the brace in adjusted position. This locking plate drops into said notch by gravity and when it is the plate is moved upwardly by means of the finger or handle 25 and the brace may then be readily lifted out of the notches in which it is seated and inserted in any pair of notches or folded into inoperati e position as may be desired.

The apertures 21 are formed in the flanges 20 of the brace a sufficient distance from the desired to release the braceends of said flanges to provide an overlap ping engagement of the brace plate with the platform plate when said brace plate is opened in longitudinal alinement with said platform plate which is desirable when the bracket is to be folded into inoperative collapsed position for transportation or storage as is shown clearly in Figs. 5 and 6 of the drawings.

The operation of the device will be understood from the foregoing description when taken in connection with the accompanying drawings and the following statement there of. When the bottom or lower rows of shingles have been nailed or laid in position in the usual manner these improved roofing brackets are brought into use and are connected with one of the upper or last row of shingles as is shown in Fig. 1, by engaging one of the notches of the nail strap 8 with nails driven into said shingles, said strap having been first slipped through the guide straps 1 on the base plate 1. After the bracket has been so secured in position the platform is swung outwardly on its connecting pivot to position it in substantially a horizontal plane and at an angle to the base plate, and the base plate 19 is swung inwardly to bring its free end into engagement with a pair of registering notches in the rack bars 6 and the head 22 thereon engaging said recesses and when it has been so positioned the locking plate 23 will drop by gravity into the recess on one of the rack bars so engaged between the wall thereof and the brace plate and thereby securely lock the brace in engagement with said recess. When the parts are so positioned the end of the brace which normally overlaps the supporting platform will be projected at an angle to said platform and form a stop to receive'the lower edge of the scaffold to be supported thereon and securely hold said board against downward movement. It is to be understood that two or more of these brackets are employed according to the length of the scaffold to be supported, said brackets being arranged in alinement and the scaffold boards mounted on the platforms thereof.

When the nail strap 8 is slipped under the straps 4 and brought into operative position the head 9 thereof will engage the lower edge of the lowermost strap and form a reliable support for the bracket, the strengthening rib or head on said head affording ample support to prevent lateral bending thereof. When it is desired to store this bracket away or to transport it the nail strap is disengaged from the supporting nail and is slipped inwardly on the base plate until it is completely housed within and the looking plate 23 is then moved out of the recess in the rack bar with which it is engaged and the free end of the brace is lifted out of its supporting notches and swung outwardly into longitudinal alinement with the platform plate and these plates are then swung inwardly on the base plate with the flanges thereof disposed between the flanges of said base plate thereby forming a compact article which may be readily stored or moved from place to place.

I claim as my invention:

A roofing bracket comprising a base plate having upstanding side flanges, a platform plate having downwardly extending side flanges with the edges thereof folded inwardly to fold reinforcing means, said platform being slit longitudinally at one end at its junction with said flanges and the portion thereof between said flanges rolled inwardly to form a hinge knuckle or sleeve, a pintle connecting said knuckle with the flanges of said base plate the opposite end of said flanges being similarly rolled to form a hinge knuckle, a brace plate having right angular flanges extending from the inner face thereof, said flanges being apertured at points spaced necting the apertured flanges with the hinge knuckle at the free end of the scaffold plate thereby forming a projection at the connected end of said brace plate the other end thereof being rolled to form a bead, and means on said base plate for detachably engaging said bead to support said brace in adjusted position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. WILLIAM H. BOYD.
